According to the establishment of the pre- 
sent .trench army, the term of regiment is 
confined to the cavalry and artillery, and the 
name ot half-brigade is given -to the infantry; 
so that chef de brigade, chief of brigade, cor- 
responds with our colonel of a regiment of 
infantry, The denomination of colonel is 
still retained in the French cavalry. 
\V ith respect to the derivation of the word, 
it appears that the best etymology is from 
tlie French word regie, management, which 
comes from the Latin regere, to govern. 
Hence a regiment is said to be governed by 
a colonel. M. Beneton, a celebrated French 
etymologist, differs from this explanation. 
He traces it from the French regime, which 
signifies system, regimen, administration, and 
which is again derived from the Latin rem- 
men, bearing the same import. In a physical 
acceptation of the term, regime (unde regi- 
men) is used to express any body that is 
composed of several others. But this is mere 
conjecture on his part. 
REGISTER, a public book, in which are 
entered and recorded memoirs, acts, and mi- 
nutes, to be had recourse to occasionally, for 
knowing and proving matters, of fact. 
Of these there are several kinds; as, 1. 
Registers of deeds in Yorkshire and Middle- 
sex, in which are registered all deeds, con- 
veyances, wills, &c. that affect any lands or 
tenements in those counties, which, are other- 
wise void against any subsequent purchasers, 
or mortgagees, &c. but this does not extend 
to any copyhold estate, nor to leases at a 
rack-rent, or where they do not exceed 21 
years. r ihe registered memorials must be in- 
grossed on parchment, under the hand and 
seal of some of the grantors, or grantees, at- 
tested by witnesses wlio are to prove the 
signing or sealing of them, and the execution 
ot the deed. 
But these registers which are confined to 
two counties, are in Scotland general, bv 
which the laws of North Britain are rendered 
very easy and regular. Of these there are 
two kinds; the one general, fixed at Edin- 
burgh, under the direction of the loru-re- 
gister ; and the other kept in the several 
shires, stewartries, and regalities, the clerks of 
which are obliged to transmit the registers of 
their respective courts to the general register. 
No man in Scotland can have a right to any 
estate, but it must become registered within 
40 days of his becoming seised thereof, by 
vvn ch means all secret conveyances are cut 
off. 2. Parish registers, are books in which 
are registered the baptisms, marriages, and 
burials, of each parish. The dissenters of all 
denominations register the births of their chil- 
dren at Dr. Wiliiatns’s library in Red Cross 
street, Cripplegate. 
Register is also used for the clerk or 
keeper of a register. Of these we have se- 
veral, denominated from the registers they 
keep; as register of the high court of dele- 
gates ; register of the arches court of Can- 
terbury; register of the court of admiralty; | 
register ot the prerogative court; register of 
the garter, &c. 
Register ships, in commerce, are ves- 
sels which obtain a permission either from 
the king of Spain, or the council of the Indies, 
to traffic in the ports of the Spanish West 
Indies, which are thus called from their being 
registered before they set sail from Cadiz for 
Buenos A) res. Each of these permissions 
costs 30,000 pieces of eight; and by the tenor 
of the cedula, or permit, they are not to ex- 
ceed 300 tons: but there is such a good un- 
derstanding between the merchants and the 
council of the Indies, that ships of 5 or 600 
tuns frequently pass unnoticed ; and though 
the quantity and quality of the merchandize 
on board are always expressed, yet, by 
means of presents, the officers both in Spain 
and the Indies allow' them to load and un- 
load vastly more than Hie permission ex- 
presses. 
Register, in printing, is disposing the 
forms on the press, so that the lines and pages 
printed on one side of the sheet fall exactly 
on those of the other. 
Register, among letter-founders, is one 
of the inner parts of the mould in which the 
printing-types are cast. Its use is to direct 
the joining the mould justly together again, 
after opening it to take out the new-cast 
letter. 
t REGLETS, or Riglets, In printing, are 
thin slips of wood, exactly planed to the size 
ot tlie body of the letter. The smaller Sorts 
are placed between the lines of poetry ; and 
both those and the larger are used in* tilling 
up- short pages, in forming the whites or dis- 
tances between the lines of titles, and in ad- 
justing the distances of the pages in the chase 
so as to form register. 
REGRATOR, or Regrater, in law, 
formerly signified one who bought wholesale, 
or by the great, and sold again by retail; but 
the term is now used for one who buys any 
wares or victuals, and sells them again* in the 
same market or fair, or within live miles 
round it. See Forestalling. 
Regrator, is also usedlfor one who fur- 
bishes up old moveables to make them pass 
for new. And masons who take off the out- 
ward surface of hewn stone, in order to whiten 
it, or make it look fresh again, are said to re- 
grate. 
REGULAR, denotes any thing that is 
agreeable to the rules of art: thus we say a 
regular building, verb, &c. 
A regular figure in geometry is one whose 
sides, and consequently angles, are equal ; 
and a regular figure with three or four sides, 
is commonly termed an equilateral triangle 
or square, as all others with more sides are 
called regular polygons. 
All regular figures may be inscribed in a 
circle. A regular solid, called also a Platonic 
body, is that terminated on all sides by re- 
gular and equal planes, and whose solid 
angles are all equal. 
The regular bodies are the five following : 
L The tetrahedron, which is a pyramid 
comprehended under four equal and equila- 
teral triangles. 2. The hexahedron, or cube, 
whose surface is composed of six equal 
squares. 3. The octahedron, which is bound- 
ed by eight equal and equilateral triangles. 
4. The dodecahedron, which is contained 
under twelve equal and equilateral pentagons. 
5. The icosihedron, consisting of 20 equal 
and equilateral triangles. These five are all 
the regular bodies in nature. See Tetrahe- 
dron, &c. 
Proportion of the five regular bodies 
inscribed in the same (circle from Peter IIo- 
rigon. Cursus Math. vol. i. p. 779. and Bar- 
row’s Euclid, lib. xiii.) :

If one of these five regular bodies was re- 
quired to be cut out of the sphere of any 
other diameter, it, will be. As the diameter of 
the sphere (2), is to the side of any one soiid 
inscribed in the same (suppose the cube,, 
1 . i 5-1/ ), so is the diameter ot any one sphere 
(suppose 8), to 9.2376, the side of the cube 
inscribed in this latter sphere. 
Let dr (Plate MisceJ. fig. 208.) be the dia- 
meter of any sphere, and da f of it =ab=br. 
Erect the perpendiculars ae, cf, and bg, and 
draw de, df, cr,fr, and gr. Then will 
I • re be the side of the tetrahedron. 
2. dj be the side of the hexahedron. 
3. de be the side of the octahedron. 
4. Cut de in extreme and mean proportion 
in h, and ch will be the side of the dodeca- 
hedron. 
5. Set the diameter dr up, perpendicu- 
larly, at r ; and from the centre c, to its top 
draw the line eg, cutting the circle in g. - 
Let foil the perpendicular*#/;, then is br the 
side of the icosihedron. 
Regular curves, such as proceed gradu- 
ally in the same geometrical manner with re- 
gard to their curvities. See Curve. 
REGULATOR of a watch, the small 
spring belonging to the balance; serving to 
adjust its motions, and make it go faster or 
slower. See Clockwork. 
RLGLLUS, in chemistry, an imperfect" 
metallic substance that falls to the bottom of 
tlie ciucible in the melting of ores, or impure' 
metallic substances. The regulus is now un- 
derstood to be the pure metal. 
Regulus, in astronomy, a star of the first- 
magnitude, in the constellation Leo; called 
also from its situation, cor leonis, or the lion’s -• 
heart. See Astronomy. 
REIN-DE TL See Cervus.- 
REJOIN DER, in law, is the defendant’s 
answer to the plaintiff’s replication or reply 
■ hlls > in tie court of chancery, the defendant 
puts m an answer to the plaintiff’s bill, which 
is sometimes also called an exception ; the 
plaintiff’s'' answer to this is called a replica- 
lon > and the defendant’s answer to that a re- 
joinder. 
R LJOINT fNG, in architecture, filling U p

ought to be performed with the best' mortar 
as that of lime and cement ; and sometimes 
with plaister, as in the joints of vaults.
